Stephen Wheeler Downey (1839-1902) was born in Maryland and was admitted to the bar in 1863. He served in the northern army during the Civil War, attaining the rank of colonel. He married during this time and had two daughters. In 1869 S.W. Downey followed a brother, William O. Downey, to Laramie. His wife died shortly after their arrival, and he married Evangeline Victoria Owen in 1872. Downey practiced law in Laramie and served in the state legislature. He drafted the bill creating the University of Wyoming; and he also attempted to develop several mines in the area.
Eva Owen Downey (1853-1937) was born in England and traveled to Salt Lake City as an infant. In 1868 her mother brought Eva, her sister Etta, and her son William east to Laramie, Wyoming, where they settled. Eva and Stephen Downey had ten children together, including Stephen Corlett (1873-1934), who became a lawyer and partner in his father’s practice; June Etta (1875-1932), who was a professor at the University of Wyoming and became nationally prominent in the field of psychology research; Sheridan (1884-1961), who pursued a political career as a liberal in California; and Alice (1892-1969), who acted as the historian of the family.
